If you have issues with your vision, contact lenses are ideal to use while avoiding the need to wear spectacles. Due to some circumstances, you may be unable to wear conventional contacts, but there is good news for you. Scleral lenses are perfect for such situations. They consist of special gas permeable (GP) contact lenses that best suit the following conditions:
GP material in conventional contact lenses does not dehydrate. If your eyes do not lubricate naturally, you may experience some discomfort after wearing them for a long time. You can still experience the same when you use eye drops to lubricate your eyes regularly. Scleral lenses are ideal for this condition. This is because they have a liquid reservoir that offers a lubricating layer on the ocular surface of your eyes.
This is a condition where your cornea has a curve that is steeper in one area than another. There are two types of astigmatism, namely, lenticular and corneal. They refer to mismatches in your lens and cornea, and both cause blurry vision. Corneal GP contacts can help remedy this condition though they can be unstable. The instability of the GP contacts can cause an intermittent visual disturbance.
If traditional lenses are not good enough to help your moderate to severe astigmatism, you will benefit from scleral contact lenses.
You are an ideal candidate for scleral contact lenses if you are suffering from an ocular surface disease. The disease involves damage to the conjunctiva and cornea layers of your eyes. Ocular surface disease (OSD) can occur due to several reasons. The two most common causes are blepharitis and dry eye syndrome.
Scleral contact lenses form a cushion that acts as a liquid dressing. The liquid dressing or bandage constantly lubricates the anterior ocular surface of your eye, protecting it from exposure. Scleral contact lenses offer quick, dramatic improvement in vision and comfort if you have OSD. This will allow you to return to your normal daily activities.
This happens when your cornea gradually thins and swells out in the shape of a cone. When your cornea swells in this shape, you will experience sensitivity to glare and light as well as blurry vision. This disease makes wearing spectacles or regular GP lenses very uncomfortable because of the irregular shape of your cornea. This condition makes you a valid candidate for scleral contact lenses.
If you are unfortunate enough to have injuries to your eyes from chemical burns, scleral contact lenses can help you. This is because the chemical burns make your corneas too sensitive to use conventional contact lenses. Your use of scleral contact lenses will depend on the nature and magnitude of your injuries.
If you are born with abnormal eyelids, scleral lenses have a better chance of helping your vision than conventional contacts.
